Lol, not how that works. Still though, there’s interference everywhere. Portable phones, Bluetooth, and even some remote controls cause interference with 2.4GHz. Even USB 3.0 ports on the computer you’re using it on cause interference.

Think of half-duplex like a walkie talkie. Communication both ways, but not at the same time.

Simplex is unidirectional like a river. That’s like basic keyboards (not the kind that have screens or get info from the PC), or a webcam or speakers.

Full duplex is like a phone call. Data is bi-directional and can be transferred both ways simultaneously.

Hope that helps with the terminology.

Cat5e or better is fine unless you’re trying to do a 10Gb network (if your router can handle that) or have long runs. Whatever you’ve got is probably fine.

50ft is fine. So long as the cable is of ok quality and less than 300ft you’re golden. Current cable isn’t like the old stuff where colling too much caused issues.

Also, this guy knows. Wireless is great, but wired is always better if possible.
